ABSTRACT:
A magnetic domain memory in which domains are driven along a structure of discrete elements which includes at least two domain detection elements formed by interconnected chevrons. The detection signal is based upon the magnetoresistive effect of the series of chevrons. The domain detection elements are pair-wise connected to inputs of a difference determining unit. The detection elements of a pair are disposed 180.degree. relative to each other in the plane of the plate, but are otherwise substantially identical. The detection elements are generally asymmetrical in the sense that a majority of pairs of successive chevron elements are interconnected in positions situated between their center and a corresponding end. Thus, upon passage of a domain within a period of the rotary magnetic field, a comparatively large and a comparatively small domain signal can periodically be generated.
